Due to higher alternator output, present V-belt tension is insufficient. Adjust belt tension as follows:
Alternator V-belts up to 1000 mm long
^
a 2 mm max. deflection with new belt
^
a 5 mm max. deflection with previously run belt
Alternator V-belts over 1000 mm long
^
a 10 mm max. deflection with new belt
^
a 15 mm max. deflection with previously run belt
Note
Extremely loud squealing may indicate damaged V-belt that should be replaced
